List of iCarly characters

The Nickelodeon sitcom iCarly (2007–2012) centers around Carly Shay, who creates her own web show with her best friends Sam and Freddie. The series stars Miranda Cosgrove as Carly, Jennette McCurdy as Sam, Nathan Kress as Freddie, Jerry Trainor as Spencer, and Noah Munck as Gibby. iCarly was created by Dan Schneider, who also served as executive producer. Two television films, iGo to Japan and iParty with Victorious, a crossover with Victorious, were released in 2008 and 2011 respectively. A joint spin-off with Victorious, titled Sam & Cat, starring McCurdy and Ariana Grande as Cat Valentine from Victorious, aired on Nickelodeon from 2013 to 2014.

In 2021, a revival of the series was released for Paramount+, with Cosgrove, Kress, and Trainor continuing their roles, and also starring Laci Mosley as Carly's best friend Harper and Jaidyn Triplett as Freddie's stepdaughter, Millicent. The series was developed by Ali Schouten without Schneider's involvement. Schouten also serves as executive producer alongside Cosgrove.

Carly Shay (Miranda Cosgrove) starts as a 13-year-old girl who lives with her older brother, Spencer Shay, in Seattle, Washington. They live in the Bushwell Plaza apartment building.

In "iPilot", Carly takes the blame for one of Sam's pranks and has to oversee people who want to be in the school's talent show as punishment. When Carly, Sam, and Freddie's suggestions are completely ignored, they decide to make a web show named iCarly upon Freddie's suggestion, with the 'i' standing for 'Internet' and Carly's name since she will be the host of the show.

In the 2021 revival, it is revealed that Carly hosted QVC whilst in Italy and hosted college radio while studying theater and media studies. By the events of the reboot, she is sharing an apartment in Seattle with her new friend Harper. After failed attempts to start an Internet channel with romantic interests, she decides to restart her iCarly webshow, with Freddie and Spencer assisting her. Carly's relationship with Freddie develops more throughout the second season, to the point where they start to fall in love with each other again, something established in the season 2 finale and stated by Freddie's then-girlfriend, Pearl.

Samantha "Sam" Puckett (Jennette McCurdy) is Carly's best friend and co-hosts the iCarly webshow with her. Sam has an identical twin sister named Melanie. Their mother is Pam Puckett (Jane Lynch).

In the series finale, "iGoodbye", Sam and Carly take a break from their web show while Carly moves to Italy. Sam becomes a lead character in the spin-off series Sam & Cat, in which she moves to Los Angeles and becomes friends with Cat Valentine (a character originally from Victorious) after rescuing her from a garbage truck.

In the 2021 revival, it is revealed that Sam had left Los Angeles and joined a biker gang that travels the country.
